The four points

Points ask; they are never voted on.

PointUse it whenInterrupts a speaker?
Point of Personal PrivilegeSomething is impairing your ability to participate: you cannot hear the speaker, the room is freezing, you need to step out.Yes, the only point that freely interrupts a speaker. Use it sparingly and only for real impairments.
Point of OrderProcedure is being broken: wrong vote threshold, skipped speaker, chair error. The chair rules on it immediately.Only if the speech itself violates procedure. During voting, only points about the conduct of the vote.
Point of Parliamentary InquiryA question to the chair about procedure: "what would this motion do?" Ask before you move something you are unsure about.No. Raise it when the floor is open.
Point of InformationA question to a speaker who has yielded to questions. In THIMUN-style procedure this is the main way to challenge a speech.No. It comes after the speech, through the chair.

Voting rules in brief

The five facts that settle most arguments at the back of the room.

Procedural votesHow the committee runs: caucuses, agenda, closure. Every delegate present must vote; no abstentions.
Substantive votesDraft resolutions and amendments. Abstentions allowed, unless you declared "present and voting" at roll call. Observer delegations do not vote.
Simple majorityMore yes than no. Abstentions do not count in the denominator.
Two-thirdsYes votes at least double the no votes. Used for closing debate, and at some conferences for unfriendly amendments or "important questions".
Voting procedure is sealedOnce voting begins, nobody enters or leaves, and only points about the vote itself (or personal privilege) are in order.
